[Bacteriological diagnosis of species of the genera Neisseria and Branhamella]

Abstract

Various technics of swabbing and isolation are described here in the search for bacteria of the genera Neisseria and Branhamella. The methods of staining the most commonly used for direct examination are mentioned, and the media of transport and isolation useful in particular for the gonococcus and meningococcus. Thus isolation of the bacteria permits during a second stage to culture and identify various species in the light of their cultural, biochemical and serological properties. The study of their sensitivity to antibiotics in vitro is easy to carry out, but it requires certain precautions and it will be described in detail in another publication.
